RxSwift Text field Delegate Methods

Question

I'm new to RxSwift. I need to ask how can I bind textField delegate methods using RxSwift like textFieldShouldReturn or textViewDidBeginEditing.

Answer 1

This will bind textfield delegate methods

textfield.rx.controlEvent([.EditingDidBegin]).asObservable().subscribe(on:{_ in 
    print("edit begin")
 }).addDisposableTo(disposer)

Answer 2

RxSwift, RxSwiftExt, RxCocoa 5.0:

let textField = UITextField()
textField.rx.controlEvent(.editingDidBegin).subscribe(onNext: { () in

}, onError: { (error) in

}, onCompleted: {

}).disposed(by: disposeBag)

Answer 3

this is one way of getting the text only when editing is done

cell.nameLabel.rx.controlEvent(.editingDidEnd).map{return
                        cell.nameLabel.text!
                    }

Answer 4

Let's supose you have a viewModel . For instance:

class ViewModel {
    var name: Variable<String>
    // more properties ...
}

Then, in your viewController :

textField.rx.text.orEmpty
    .bindTo(viewModel.name)
    .addDisposableTo(disposeBag)

In your viewController you have to import RxSwift and RxCocoa
